Going to a concert while in 2ww, second hand smoke, safe?

My fiance really wants to go to this concert tonight, we've been planning this for a month. We are also TTC and I am in my 2ww, and I feel I stand a good chance of being pregnant as we speak. I really feel that I am. There may be smoking of cigarettes at this venue. I do not smoke, however. Should I stay away? I wish I would have thought of this earlier l, but I don't know, I haven't been feeling well, and I have been preoccupied. We are already half way through with the 3 hour road trip to get to the place. If y'all say not to go, I'm sure I can find something else to do once we get to the city.
